Definitions

  • the present invention relates to an internal combustion engine, for the propulsion of ships carrying a combustible gas, and more particularly of LNG ships.
  • a partition of the cylinders of an engine is also known, but for another purpose: GB-A-738 451 proposes an engine having two groups of cylinders, one comprising the cylinders having a new lining, supplied with light oil, then after running in, with heavy oil, and the other group, comprising cylinders with lining already run in, permanently running on heavy oil.
  • the subject of the present invention is a method of supplying a fuel engine comprising two groups of cylinders for the propulsion of ships carrying a combustible gas consisting in supplying a first group of cylinders with the same fuel, and in supplying the other group of cylinders, selectively, either by the same fuel or by a different fuel.
  • the method consists in supplying the first group of cylinders with a fuel, for example liquid.
  • the method can also consist in supplying the first group of cylinders with a gaseous fuel.
  • the invention also relates to a method of supplying an internal fuel engine for the propulsion of ships carrying a combustible gas, the engine comprising three groups of cylinders, consisting in supplying said first and second group of cylinders always by a same fuel, said first group of cylinders being supplied by a gaseous fuel and said second group of cylinders being supplied by liquid fuel, and consisting in supplying said third group of cylinders selectively either by said liquid fuel or by said gaseous fuel.
  • the method consists in grouping the first and third groups of cylinders into a first engine and the second group of cylinders into a second engine.
  • the invention also relates to a method of supplying an internal combustion engine for propelling ships carrying a combustible gas, this engine comprising four groups of cylinders, consisting in supplying a first, a second and a third group of cylinders always on the same fuel, the first group of cylinders being supplied by gaseous fuel, the second and third groups of cylinders being supplied by liquid fuel, the fourth group of cylinders being selectively supplied either by liquid fuel or by gaseous fuel, the first and second groups of cylinders being grouped into a first engine, the third and fourth groups of cylinders being grouped into a second engine.
  • Figure 1 shows an engine with two groups of cylinders.
  • Figure 2 shows an assembly with three groups of cylinders.
  • Figure 3 shows an assembly with four groups of cylinders.
  • the engine is referenced 10 while the propeller is referenced 1.
  • the engine 10 comprises two groups of cylinders 11 and 12, one group, for example 11, being always supplied by the same fuel (either liquid or gaseous), the other group 12 being selectively supplied by the liquid fuel or by the fuel gaseous.
  • the engine can consist, for example, of two rows of vee cylinders.
  • the assembly of FIG. 2 comprises three groups of cylinders, a group 11 permanently supplied by the gaseous fuel, a group 12 selectively supplied either by the liquid fuel or by the gaseous fuel, and a group 13 permanently supplied by liquid fuel.
  • Group 11 and group 12 come together to constitute a first motor, the group 13 constituting, by itself, a second motor.
  • a reduction gear 2 transmits the power of each of the engines to the propeller 1.
  • the three groups of cylinders could be combined into a single engine.
  • the assembly of FIG. 3 comprises four groups of cylinders, associated two by two to constitute two engines 11, 13A, and 12, 13B.
  • Groups 13A and 13B are powered by liquid fuel.
  • Group 11, associated with group 13A is always supplied by gaseous fuel.
  • Group 12, associated with group 13B is selectively supplied either by liquid fuel or by gaseous fuel.
